UdpTsPcapPcrStats
A PCR (Program Clock Reference) measurement for one PCR pid, surfaced from the UDP-TS passive probe (id3as-ts EtrAnalyser, WallClock mode). Measured values (not pass/fail counters), so no "not observable" wrapping — the list is simply empty until enough samples exist. See oxidized/id3as-ts/src/etr.rs PcrMeasurement.

Description |
Experimental. Passive-probe UDP-TS stats, set only for a pcap-derived UDP-TS input (the input.capture udp-ts arm); unset for every other input kind. Rides the TS connection health sample. The ETR-290 running counters reuse the QualityReportingTsErrors field-set (same id3as-ts TsErrorMetrics); bitrate is "not observable" (unset, never 0) on a zero/tiny capture span. Field semantics: oxidized/udp-ts-probe/src/stats.rs + id3as-ts TsErrorMetrics. |
